MACHINE FOR MAKING WINDOW-ENVELOP BLAN'KS.

Specification 0! Letters Patent.

Patented Nov. 24, 1914.

Application filed September 20, 1912. Serial No. 721,392.

parent window in the face thereof.

The object of my improvements is to provide means for rapidly and accurately furnishing envelop blanks embodying those features particularly characteristic of envelops of the character specified.

The machine of this application is adapted for producing envelop blanks in accordance with the subject matter of my copending application for Letters Patent of the United States for improvements in the process of making window envelop blanks,

Serial Number 712411, filed July 31,1912, and to which reference may be had.

\Vith these ends in view I preferably em- I ploy mechanism illustrated in the drawings accompanying this specification wherein- Figure 1 is a diagrammatic sectlonal elevation of my improved machine. F g. 2 is an elevation, to an enlarged scale, illustrating a detail of my improved machine. Fig. 3 is a plan view of a window envelop blank as produced in said machine. Fig. 4 is a diagrammatic elevation illustrating the arrangement of gearing and some of the cam mechanism. Fig. 5' is a fragmentary side elevation illustrating a modification of a portion of my improvements.

Mounted on supports as 2, and resting against rail 3, is a pile of ordinary envelop .blanks 4. In front of and near the lower delivering that blank to the grip of clips,

as 10, on cylinder 5.

I have illustrated suction means for engaging said front blank. Flnger 7 is of tubular construction and is provided near its lower end with ports 9. Air may be exhausted at suitable times through hollow shaft 8 by some suitable exhaust means.

For oscillating finger 7 I provide arm 41 fixed to shaft 8 and having at its lower end roll 42 for engagement with cam 43 fixed to shaft 6. Clips, as 10, are fixed to shaft 44, as is arm having roll 146 for engagement with fixed cam 147. Said cam 147 may be held in fixed position relatively to cylinder 5 by some convenient well known means, not shown.

To the right of cylinder 5 and coacting therewith is rotary blank-bed or platen cylinder 11 on shaft 12. Said cylinder is provided with clips as 13, for gripping the blank. Said cylinder may also be provided with one member 14 of a pair of cutting dies. The other member 16 of said pair of cutting dies may be mounted in cylinder 17 on shaft 18 above cylinder 11. Said dies 14, 1.6 are efiicient for cutting the window opening as 20 in the-blanks as 40, Fig. 3. Said clips, as 13, are-fixed to shaft 46, as is arm 47 having roll 48 for engagement with fixed cam 49. I

For removing the severed window blank from the envelop blank I provide die 16 with spear 50 which, as dies 14, 16 coact, pierces the window blank portion of the envelop blank in coaction with the window blank supporting edges of pocket 83 in die 14 of rotary bed 11; and when that window blank portion is severed from the envelop blank, conveys it upwardly around cylinder 17 where it may be removed from said spear by means of stripper 51 mounted for reciprocation radially in cylinder 17. Said stripper is provided with, roll 52 for coaction with fixed cam 53. Above cylinder 11 rotary gummer 19 is fixed to shaft 21 and adjacent to the upper portion of the path of travel of said gummer is gum delivery mechanism 22.

To the right of cylinder 11 is the mecha-' nism for delivering consecutively to the gummed faces of the blanks respectively, patches of transparent paper. This mechanism comprises a shaft 23 for holding a roll, as 36, of transparent paper in an endless strip, upper and lower feed rolls 24, 25 fixed oscillating cutter 27, above the path of said.

strip, for coaction with lower cutter 26.

Rotary patch-bed or delivery cylinder 28 fixed to shaft 39, is provided with grippers as 29, and which grippers may be mounted for retraction below the periphery of said cylinder 23. Said grippers, as 29, are fixed to shaft 51 in the free end of arm 55 and which arm is fixed to shaft 30 in cylinder 28. Also fixed to shaft 5% is arm 56 having roll 57 for engagement with fixed cam 58. Springs 59 and 60 are arranged for urging clips, as 29, to their inoperative positions, spring 59 being weaker than spring 60, whereby said clips, as roll 57 passes around cam 58, will be first moved outwardly and then downwardly into coaction with the periphery of cylinder 28 for gripping the leading end of a patch portion 33.

For feeding web 32, rolls 24:, 25, are geared together by gears 61, 62, and coaxially fixed with roll 25 is ratchet 63. Said ratchet may be rotated intermittently from cam 64 by the usual mechanism therefor, particularly illustrated in Fig. 1. For 0*- cillating upper knife 27 I employ cam 65, mounted for rotation with" cylinder 28. Said knife is fixed to the outer end of arm 66, freely pivoted on shaft 67 of roll 24, and said arm 66 is operatively connected with cam 65 by the usual means. In some cases I may use rotary cutters as illustratedin Fig. 5 in preference to reciprocating cutter 27 and fixed cutter 26. By. the employment of rotary cutters web 32 may be fed continuously if desired rather than intermittently as illustrated in Fig. 1'.

Below cylinders 11. and 28 are coacting delivery .rolls 37, 38 and .below said dolivery rolls is receiving box 70. Said box is provided with oscillating presser 69 for pressing the envelop blanks to one side as they fall one after another from rolls 37, 38. Said presser is actuated from cam 71 fixed to shaft 6, by means of the usual connections.

For driving and timing the several instrumentalities of my improved machine I provide the following means: Considering shaft 6 as the main or primary shaft, and which shaft may be rotated from some source of power by some convenient well known means not shown, I fix to said shaft 6 gear 7 5 which drives gear 7 6 on shaft 12. Said gear 76 in turn drives gear 77 on shaft 18, gear 78 on shaft 21 and gear 79 on shaft Gear 81 on shaft 74: is driven from gear 7 9 through intermediate 80, and drives gear 82 on shaft 73.

The operation of my improved machine. is as follows: A quantity of envelop blanks of suitable profile being placed upon rods as 2, and against bar 3, shaft 6 is started in anti-clockwise direction. Finger '2' is thereby oscillated to its dotted position where it engages the lower end of the foremiaaee most blank. Said finger then swings to the right into a channel provided therefor in the periphery of cylinder, 5 and delivers the lowermost end of that blank into the grip of clips, as 10. Said cylinder 5 then rotating in anti-clockwise direction carries said blank downwardly and then upwardly to engagement with cylinder 11, whereupon grippers as 13, of that cylinder, grip the leading end of the blank. GripperslO then release their hold and the blank is carried around upwardly on cylinder 11. Said blank extends over cutting die 14 on said cylinder, and as it passes under cutting die 16 on cylinder 17, a window opening as 20 will be cut therein. As said dies roll into engagement spear 50 will pierce the window blank portion of said envelop blank and as die 16 travels upwardly on cylinder 17, said window blank portion will be removed from the envelop blank by means of said spear and from said spear by means of stripper 51. The blank now moves onwardly with cylinder 11 under glimmer 19 which deposits gum 31 thereon around the border of window opening 20, Fig. 3. During this operation web 32, of transparent paper, from roll 36, has been advanced by feed rolls 2%, 25, over lower knife 26, in position to be gripped by-clips as 29, of delivery cylinder 28. Just as said clips reach the position shown in Fig. 1, knife 27 descends and cuts from web 32 a patch portion 33 and into the grip of delivery rolls 37, 38 by which it is discharged onto receiving rods 1.
